A custom kernel often uses less memory. The kernel is the one system component that must always be present in memory, so unused code ties up memory that would otherwise be available to the virtual memory system. On a system with limited RAM, you can save some memory by building a custom kernel, but don’t overestimate the savings: a minimal kernel might save 500 kB over the GENERIC kernel supplied with the system.
